Process Algebra Based Tool Coordination Architectures in Raku and Go

This paper presents ongoing research in our project software engineering with process algebra. In this project we have developed among others a reimplementation of the simulator from the PSF Toolkit, a set of tools for the Process Specification formalism (PSF). This new simulator uses the ToolBus, a tool coordination architecture based on process algebra. We now developed new tool coordination architectures based on this ToolBus. We implement the primitives of the ToolBus in the programming languages Raku and Go. Both these languages have support for concurrency and communication between concurrent entities in the form of channels. We apply these tool coorination architectures on a small example. And we give implementations for the simulator in the PSF Toolkit based on the tool coordination architectures in Raku and Go.
